| ABSTRACT |
|
In a retrospective study of 52 patients who underwent elective surgery for cerebral arteriovenous malformation, statistical analysis of elements of AVM was undertaken, in order to discover the predictors of operative morbidity. All patients had a computed tomographic scan and the positive angiogram before surgery. Elements of AVM contains Indus, arterial feeders and draining veins. The size of nidus was classified by Yasargil's method. The results were same as below; 1) Size:Giant-6 cases, large-7 cases, moderate-7 cases, small-13 cases. 2) Arterial feeders:ACA-16 cases(23%), MCA-32 cases(45%), PCA-14 cases(20%), AnCh-4 cases(6%), SCA-1 case(1%), Post. Choroidal-2 cases(3%), Call. Marginal-1 cases(1%), Opthalmic-1 case(1%). 3) Type of venous drainage:type A-10 cases, type B-3 cases, type C-7 cases, type D-4 cases, type E-9 cases, type F-2 cases. |
